A lot of experience, but still learning...
I work as a developer since 1997.
Over the time I have gained experience with various languages and frameworks.
I am not a "one field" expert, although my best knowledge is of Perl and Java languages.
I have developed and maintain Perl based system for sequence
EDI messages processing for automotive suppliers of VW.
For 5 years I took part in development of Java based warehouse
management system. This is server side system with browser-based
client, running on Tomcat application server and Microsoft SQL Server
database. Part of the solution is telnet (VT100) client running
on wireless barcode scanners.
Since 2007 I do development in the field of SAP PI (Process
Infrastructure, former SAP XI). This includes among others Java
and XSLT development.
